ANTON HEIM, OF NEW YORK, N.Y.

MACHINE FOR WRINGING RAW HIDES AND LEATHER.

SPECIFICATION forming part Of Letters Patent No. 297,260, dated April22, 1884-. Application filed June 14, 1883. (No model.)

To all whom it may concern:

Be it known that I, ANTON HEIM, of the city, county, and State of NewYork, have invented certain new and useful Improvements in Machines forWringing Raw Hides and Leather, of which the following is aspecification.

In the manufacture of articles of leathersuch as leather belting,lace-leather, pickerleather, and for other purposesth'e raw hides orleather are saturated with liquids to a considerable extent andafterward dried in the drying-rooms.

To accelerate the drying process, a part of the moisture'has heretoforebeen removed by placing the leather or hides in a press, by whichmethod, however, the moisture could be removed only in an imperfectmanner.

My invention is designed to furnish awringing-machine by which raw hidesor leather saturated with moisture can be freed of the greater part ofsaid moisture; and the invention consists of a machine for wringing rawhides or leather, composed of a supportingframe, a lower revolving rollturning in fixed bearings and covered with ropes or a suitable textilefabric that exerts a frictional contact upon the hide or leather, anupperrevolving roll covered by similar material and turning invertically-movable and spring-cushioned bearings, the upper rollreceiving motion from thelower roll by an intermediatetransmittinggearing, so that the hide or leather that is passed throughbetween the rolls is freed by the pressure of the same of the greaterpart of the moisture contained therein.

In the accompanying drawings, Figures 1 and 2 represent side elevationsof my improved machine for wringing raw hides and leather, showing thesame from opposite sides; and Figs. 3 and 4: are a vertical transverseand a vertical longitudinal section of one of the pressure-rolls.

Similar letters of referenceindicate corresponding parts.

- Referring to the drawings, A represents the supporting-frame of myimproved machine for wringing raw hides or 1eather,which frame consistsof two uprights, a, that are connected by top and bottom pieces, b Z),and stays 01.

At one side of the frame A is supported a horizontal table, 13, on whichthe raw hide or leather is spread out, so as to be fed forward to theaction of two wringing-rolls, O and D, which are supported in bearings Cand D of the supporting-frame A. The bearings O of the lower roll, 0,are rigidly secured to the frame A, while the bearings D of the upperroll, D, are cushioned by strong spiral springs e e, that are interposedbetween the bearings D and fixed plates 6 of the vertically-adjust ablescrews E, that pass through the top pieces, I) b, said screws havinghand-wheels e at their upper ends. By adjusting thescrews E lower orhigher the tension of the spiral springs e e is regulated and the upperroll, D, applied with more or less pressure on the wet hide or 7 leatherthat is passed through between the rolls 0 and D. The upper roll, D,adjusts itself automatically to the thickness of the hide or leatherworked upon by the machine. The rolls 0 and D are covered with a hair orother rope, which is wound spirally around the same, as shown in Figs. 3and 4:; or the rolls may be covered by any suitable textile fabric-suohas canvas-or by other equivalent material, by which the proper degree offriction is exerted upon the hide or leather, so that the same is drawnthrough between the rolls without slipping or escaping therefrom. Thelower roll, 0, receives motion from apower-shaft, g, and pinion g, whichlatter meshes with a gearwheel, 9 on the shaft of the lower roll, 0. Atthe other end of the shaft of the lower roll, 0, is another gear-wheel,which meshes with an intermediate gear-wheel, supported in bearings offrame A. This gear-wheel meshes with a second intermediate gear-wheel, 9which is supported in bearings of frame A above the bearings of thegear-wheel g. The gear-wheel g meshes with a gear-wheel, g, on the shaftof the upperroll, D. Bymeans of the intermediate gear-wheels describedthe upper roll is revolved at the same degree of speed as and inopposite direction to thelower roll, 0, so that the hide or leather istaken hold of by the pressure of the rolls, drawn through between them,and freed by the pressure of the greater part of moisture containedtherein,

I am aware that machines 'for rollingleather in which the leather ispassed through revolv- I said rolls, and a supporting-frame, substan- 1oing rolls have been used heretofore, and I I tially as described.

therefore do not broadly claim the same. i I11 testimony that I claimthe foregoing as Having thus described my invention, I claim myinvention I have signed my name in presas new and desire to secure byLetters Patentence of two subscribing witnesses.
